These black anodised aluminium bezels will make the 0.28` voltmeters in your mods look neater.

Simply cut a hole big enough to fit the bezel into, epoxy it to the case and your voltmeter will slot straight in. Then secure the voltmeter with another drop of epoxy.

The cutout needs to be approx 24.5mm x 12mm but because of the bezel lip, it can be slightly more.
The overall size of the bezel is 27mm x 14mm so as long as your cutout is less than this, it will work.
